Multumesc!

Answer 1

a) 4 km + 2 hm + 15 dam + 279 m = ? m

4 000 m + 200 m + 150 m+ 279 m =4 629 m

b) 15km - 2 860m + 164 hm + 780 hm - 86 875m = ?m

15 000 m - 2 860 m + 944 hm - 86 875 m =

= 12 140 + 94 400 m - 86 875 m =

= 106 540 m - 86 875 m =

= 19 665 m

c) 116 km - 2 400 dam - 840 hm + 2 000m = ? dam

11 600 dam - 2 400 dam - 8 400 dam + 200 dam =

= 9 200 dam - 8 400 dam + 200 dam =

= 800 dam + 200 dam =

= 1 000 dam

d) 68 000 m + 27 500 hm + 4 800 dam - 1 998 km = ? km

= 68 km + 2 750 km + 48 km - 1 998 km =

= 2 818 km + 48 km - 1 998 km =

= 2 866 km - 1 998 km =

= 868 km

e) 4 800 dam - 39 600 m +14 km - 1 970 dam = ? hm

= 480 hm - 396 hm + 140 hm - 197 hm =

= 84 hm + 140 hm - 197 hm =

= 224 hm - 197 hm =

= 27 hm

f) 24 600 dam - 198 000 m + 190 hm - 5 900 dam = ? km

= 246 km - 198 km + 19 km - 59 km =

= 48 km + 19 km - 59 km =

= 67 km - 59 km =

= 8 km

g) 16 km +16 hm + 16 dam - 16 166 m = ? m

= 16 000 m + 1 600 m + 160 m - 16 166 m =

= 17 600 m + 160 m - 16 166 m =

= 17 760 m - 16 166 m =

= 1 594 m

h) 81 km - 650 hm + 38 dam - 15 697 m = ? m

= 81 000 m - 65 000 m + 380 m - 15 697 m =

= 16 000 m + 380 m - 15 697 m =

= 16 380 m - 15 697 m =

= 683 m
